Adapter ESATTO 3.5" LP for Veloce RH300

This adapter enables the installation of the PrimaLuceLab ESATTO 3.5" LP low-profile robotic focuser onto Officina Stellare Veloce RH300 athermal astrographs. With a minimal optical thickness of just 9mm, it preserves precious backfocus distance while maintaining the full capability of the focuser's 90mm aperture and 10mm travel. When combined with the ESATTO 3.5" LP focuser on the Veloce RH300, astronomers retain 116mm of backfocus for imaging trains including cooled cameras, motorized filter wheels, and off-axis guiders, making it essential for precise wide-field astrophotography on this premium telescope.
